The first mounting seat 13 and the second mounting seat 14 are arranged in parallel along the track direction of the first guide rail 12, which means that the first mounting seat 13 and the second mounting seat 14 are arranged in a front-to-back relationship along the track direction of the first guide rail 12. This embodiment does not limit the specific structure of the first drive device either. For example, the first drive device may include a first screw rod 15, and the first mounting seat 13 is provided with a threaded hole that cooperates with the first screw rod 15. A bearing seat may be provided on the first base 11, and the first screw rod 15 is rotatably arranged on the bearing seat through a bearing. The first mounting seat 13 is arranged on the side of the first guide rail 12 close to the bearing seat, and the second mounting seat 14 is arranged on the side of the first guide rail 12 away from the bearing seat. A first driving handle may also be provided on the first screw rod 15, and the first driving handle is used to drive the first screw rod 15 to rotate.

[0026] In the embodiment of the present invention, the second adjustment assembly may further include a second base 21, and the second guide rail 22 and the second driving device are both arranged on the second base 21. The present embodiment does not limit the specific structure of the second guide rail 22, and the structure of the second guide rail 22 may be the same as that of the first guide rail 12. The third mounting seat 23 and the fourth mounting seat 24 are arranged in parallel along the track direction of the second guide rail 22, which means that the third mounting seat 23 and the fourth mounting seat 24 are arranged in a front-to-back relationship along the track direction of the second guide rail 22. This embodiment does not limit the specific structure of the second driving device. For example, the second driving device may include a second screw rod 25, a fourth mounting seat 24 is provided with a threaded hole matched with the second screw rod 25, a bearing seat is provided on the second base 21, the second screw rod 25 is rotatably provided on the bearing seat through a bearing, the first guide rail 12 and the second guide rail 22 are provided in parallel, when the bearing seat on the first base 11 and the bearing seat on the second base 21 are provided at the same end, and the third mounting seat 23 for installing the first shooting platform is provided on the side of the second guide rail 22 close to the bearing seat, then the fourth mounting seat 24 is provided on the side of the second guide rail 22 away from the bearing seat. A second driving handle is provided on the second screw rod 25, and the second driving handle is used to drive the second screw rod 25 to rotate.

[0027] In the embodiment of the present invention, two shooting platforms are installed, and two mounting seats are respectively provided on the first guide rail 12 and the second guide rail 22 as an example for explanation, but it is not limited thereto. For example, three guide rails may be provided, and three mounting seats are provided on each guide rail. The present embodiment does not limit the specific structures of the first mounting seat 13, the second mounting seat 14, the third mounting seat 23, and the fourth mounting seat 24. For example, the first mounting seat 13, the second mounting seat 14, the third mounting seat 23, and the fourth mounting seat 24 may be provided with shooting platform mounting holes and shooting platform positioning holes. The threaded hole structure on the first mounting seat 13 and the threaded hole structure on the fourth mounting seat 24 may be a detachable structure, so that the first mounting seat 13, the second mounting seat 14, the third mounting seat 23, and the fourth mounting seat 24 may first be made into four identical parts, and then the threaded hole structure may be installed on the first mounting seat 13 and the fourth mounting seat 24.

[0028] An embodiment of the present invention provides a parallel double-shooting platform adjustment device, wherein a first mounting seat 13 and a second mounting seat 14 are slidably arranged on a first guide rail 12, and a third mounting seat 23 and a fourth mounting seat 24 are slidably arranged on a second guide rail 22. The first guide rail 12 and the second guide rail 22 are arranged in parallel, and a first driving device and a second driving device can respectively drive the first mounting seat 13 and the fourth mounting seat 24 to move. When the first shooting platform is mounted on the first mounting seat 13 and the third mounting seat 23, and the second shooting platform is mounted on the second mounting seat 23 and the fourth mounting seat 24, the first driving device drives the first mounting seat 13 to move along the first guide rail 12. Since the first shooting platform connects the first mounting seat 13 and the third mounting seat 23, the third mounting seat 23 moves along the second guide rail 22 driven by the first shooting platform, thereby realizing that the first driving device drives the first shooting platform to move along the first guide rail 12 and the second guide rail 22 arranged in parallel. Similarly, the second driving device can drive the second shooting platform to move along the first guide rail 12 and the second guide rail 22 arranged in parallel. The first driving device and the second driving device can drive the first shooting platform and the second shooting platform to move along the first guide rail 12 and the second guide rail 22 respectively. During the injection molding work, the positions of the first shooting platform and the second shooting platform can be adjusted according to actual needs, thereby improving the flexibility of adjusting multiple shooting platforms in the multi-material injection molding machine, and the overall structure is simple and compact.

[0029] In another embodiment of the present invention, the first adjustment assembly further includes a first end stopper 161 and a second end stopper 162, wherein the first end stopper 161 is used to prevent the first mounting seat 13 from being separated from the first guide rail 12, and the second end stopper 162 is used to prevent the second mounting seat 14 from being separated from the first guide rail 12;

[0030] The second adjustment assembly further includes a third end stopper 261 and a fourth end stopper 262 , wherein the third end stopper 261 is used to prevent the third mounting seat 23 from being separated from the second guide rail 22 , and the fourth end stopper 262 is used to prevent the fourth mounting seat 24 from being separated from the second guide rail 22 .

[0031] In the embodiment of the present invention, there is no limitation on the specific structures of the first end limiter 161, the second end limiter 162, the third end limiter 261 and the fourth end limiter 262. For example, the first end limiter 161, the second end limiter 162, the third end limiter 261 and the fourth end limiter 262 can be cylindrical rubber roller structures, the first end limiter 161 and the second end limiter 162 can be respectively arranged at the two ends of the first guide rail 12, and the third end limiter 261 and the fourth end limiter 262 can be respectively arranged at the two ends of the second guide rail 22.

[0032] A parallel multi-shooting platform adjustment device provided in an embodiment of the present invention can effectively prevent the first mounting seat 13 and the second mounting seat 14 from being separated from the first guide rail 12, and the third mounting seat 23 and the fourth mounting seat 24 from being separated from the second guide rail 22 when adjusting the positions of the first shooting platform and the second shooting platform by respectively setting a first end limiter 161 and a second end limiter 162 at both ends of the first guide rail 12, and respectively setting a third end limiter 261 and a fourth end limiter 262 at both ends of the second guide rail 22.

[0033] In another embodiment of the present invention, the first adjustment assembly further includes a first intermediate stopper 17, the first intermediate stopper 17 is disposed on one of the first mounting seat 13 and the second mounting seat 14, and the first intermediate stopper 17 is used to limit the distance between the first mounting seat 13 and the second mounting seat 14;

[0034] The second adjustment assembly further includes a second intermediate limiter 27 , which is disposed on one of the third mounting seat 23 and the fourth mounting seat 24 , and is used to limit the distance between the third mounting seat 23 and the fourth mounting seat 24 .

[0035] In the embodiment of the present invention, the specific structure of the first intermediate stopper 17 and the second intermediate stopper 27 is not limited. For example, the first intermediate stopper 17 and the second intermediate stopper 27 may be an "L"-shaped structure. In this embodiment, the first intermediate stopper 17 is arranged on the side of the first mounting seat 13 close to the second mounting seat 14, and the second intermediate stopper 27 is arranged on the side of the fourth mounting seat close to the third mounting seat. The first intermediate stopper 17 and the second intermediate stopper 27 may be respectively arranged on the first mounting seat 13 and the fourth mounting seat 24 by screws.

[0036] A parallel multi-shooting platform adjustment device provided in an embodiment of the present invention can ensure that the first shooting platform and the second shooting platform always maintain a safe distance during the position adjustment process by respectively setting a first intermediate limiter 17 and a second intermediate limiter 27 between the first mounting seat 13 and the second mounting seat 14 and between the third mounting seat 23 and the fourth mounting seat 24, thereby avoiding collision between the first shooting platform and the second shooting platform.

[0037] In another embodiment of the present invention, the first adjustment assembly further includes a first displacement limiter 18, the first displacement limiter 18 is disposed between the first mounting seat 13 and the second mounting seat 14, and the first displacement limiter 18 is used to limit the position of the first mounting seat 13 moving toward the second mounting seat 14 and the position of the second mounting seat 14 moving toward the first mounting seat 13;

[0038] The second adjustment assembly also includes a second displacement limiter 28, which is disposed between the third mounting seat 23 and the fourth mounting seat 24, and is used to limit the position of the third mounting seat 23 moving toward the fourth mounting seat 24 and the position of the fourth mounting seat 24 moving toward the third mounting seat 23.

[0039] In the embodiment of the present invention, there is no limitation on the specific structure of the first displacement limiter 18 and the second displacement limiter 28. For example, the first displacement limiter 18 and the second displacement limiter 28 may be in a "7"-shaped structure. The first displacement limiter 18 may be arranged on the first base 11 between the first mounting seat 13 and the second mounting seat 14, and the second displacement limiter 28 may be arranged on the second base 21 between the third mounting seat 23 and the fourth mounting seat 24. At the same time, a limiting rib structure 231 may be arranged on the first mounting seat 13, the second mounting seat 14, the third mounting seat 23 and the fourth mounting seat 24. The limiting rib structure 231 is used to cooperate with the first displacement limiter 18 and the second displacement limiter 28 respectively. When the limiting rib structure 231 contacts the first displacement limiter 18 or the second displacement limiter 28, the mounting seat where the limiting rib structure 231 is located cannot continue to move along the original direction.

[0040] An embodiment of the present invention provides a flat multi-shooting table adjustment device, by setting a first displacement limiter 18 on the first base 11 between the first mounting seat 13 and the second mounting seat 14, and setting a second displacement limiter 28 on the second base 21 between the third mounting seat 23 and the fourth mounting seat 24. When the working position of the first shooting table and the second shooting table is adjusted according to actual needs, the positions of the first mounting seat 13 and the second mounting seat 14 moving toward the first displacement limiter 18 on the first guide rail 12 and the positions of the third mounting seat 23 and the fourth mounting seat 24 moving toward the second displacement limiter 28 on the second guide rail 22 are effectively controlled.

[0041] like Figure 4-5 As shown, in another embodiment of the present invention, a multi-material injection molding system is provided, comprising a first shooting platform 4, a second shooting platform 5 and the above-mentioned parallel multi-shooting platform adjustment device;

[0042] The first shooting platform 4 is disposed on the first mounting seat 13 and the second mounting seat 23 of the parallel multi-shooting platform adjustment device; the second shooting platform 5 is disposed on the third mounting seat 14 and the fourth mounting seat 24 of the parallel multi-shooting platform adjustment device.

[0043] In the embodiment of the present invention, there is no limitation on the specific structures of the first shooting station 4 and the second shooting station 5. The first shooting station 4 and the second shooting station 5 can be used to inject different molten plastics into the mold.

[0044] In the embodiment of the present invention, the multi-material injection molding system also includes a machine station positioning member 3, the machine station positioning member 3 includes a first station positioning ring structure 31, a second station positioning ring structure 32 and an intermediate station positioning ring structure 33, the centers of the first station positioning ring structure 31, the second station positioning ring structure 32 and the intermediate station positioning ring structure 33 are on the same straight line; the parallel multi-shooting platform adjustment device is used to adjust the positions of the first shooting platform 4 and the second shooting platform 5 relative to each station on the machine station positioning member 3, for example, the first shooting platform 4 and the second shooting platform 5 can be adjusted to align with the first station and the second station respectively, or one of the first shooting platform 4 and the second shooting platform 5 can be adjusted to align with the intermediate station.

[0045] In the embodiment of the present invention, the first shooting platform 4 and the second shooting platform 5 can be fixed on the first mounting seat 13 and the second mounting seat 14 and the third mounting seat 23 and the fourth mounting seat 24 by bolts, but not limited thereto. Preferably, the first shooting platform 4 can be arranged on the first mounting seat 13 and the second mounting seat 14 by a first linear motion mechanism, and the second shooting platform 5 can be arranged on the third mounting seat 23 and the fourth mounting seat 24 by a second linear motion mechanism, wherein the first linear motion mechanism and the second linear motion mechanism can be respectively used to drive the first shooting platform 4 and the second shooting platform 5 to move toward or away from the machine station positioning member 3. This embodiment does not limit the first linear motion mechanism and the second linear motion mechanism, for example, the first linear motion mechanism and the second linear motion mechanism can be a cylinder, a hydraulic cylinder or an electric push rod.

[0046] An embodiment of the present invention provides a multi-material injection molding system. By setting the above-mentioned parallel multi-shooting platform adjustment device, the positions of the first shooting platform 4 and the second shooting platform 5 can be adjusted separately according to the corresponding different workstation requirements of different shooting platforms, thereby improving the flexibility of adjusting the multi-shooting platform according to actual usage requirements.

[0047] The working principle of a multi-material injection molding system provided by the present invention is as follows: the multi-material injection molding system can be used as a double-station system (the first injection station 4 is aligned with the first station, and the second injection station 5 is aligned with the second station) or as a single-station system (one of the first injection station 4 and the second injection station 5 is aligned with the middle station). Figure 4 As shown, when used as a double station, the first screw rod 15 is adjusted to drive the first shooting platform 4 to move until it is aligned with the first station positioning ring structure 31, and the second screw rod 25 is adjusted to drive the second shooting platform 5 to move until it is aligned with the second station positioning ring structure 32. At this time, the center distance between the two shooting platforms is 2A (2A ≥ S1). Figure 5 As shown, when used as a single station, taking the adjustment of the second shooting platform 5 to the intermediate station positioning ring structure 33 as an example, the first shooting platform 4 is adjusted by the first linear moving mechanism to move a safety distance S2 away from the machine station positioning member 3, and the first shooting platform 4 is adjusted by the first screw 15 to move a distance B away from the second shooting platform 5. At this time, the center distance between the two shooting platforms is A+B, that is, the safety distance S1=A+B, which meets the use requirements of one shooting platform.

[0048] The adjustment process from the double station to the middle station is as follows: first, the first shooting platform 4 is adjusted to move a distance B in the direction away from the second shooting platform 5 by the first screw rod 15. At this time, the first end stopper 161 can limit the distance of the first shooting platform 4 moving away from the second shooting platform 5, for example, it can be moved until the first mounting seat 13 contacts the first end stopper 161; then, the second shooting platform 5 is adjusted to move a distance A in the direction close to the first shooting platform 4 by the second screw rod 25, and is aligned to the middle station. At this time, the first displacement stopper 18 and the second displacement stopper 28 can limit the movement position of the second shooting platform 5 in the direction close to the first shooting platform 4. For example, the first displacement stopper 18 and the second displacement stopper 28 can be set at the setting positions on the first base 11 and the second base 21 respectively, so that the limit rib plate structure on the second mounting seat 14 contacts the first displacement stopper 18, and when the limit rib plate structure on the fourth mounting seat 24 contacts the second displacement stopper 28, the second shooting platform 5 can be aligned to the middle station. The first end stopper 161, the second end stopper 162, the first displacement stopper 18 and the second displacement stopper 28 can also serve as positioning references during the work position adjustment, thereby facilitating the alignment adjustment of the shooting platform and improving the adjustment efficiency. In addition, the first intermediate limiter 17 and the second intermediate limiter 27 in the parallel multi-shooting platform adjustment device also have an error prevention function. For example, in the process of adjusting from the double station to the intermediate station, when the second shooting platform 5 needs to be adjusted to the intermediate station, the correct operation at this time needs to first adjust the first screw rod 15 to make the first shooting platform 4 away from the second shooting platform 5. If the second screw rod 25 is directly adjusted on the basis of the double station to move the second shooting platform 5 to the intermediate station, it is very likely to cause a collision between the first shooting platform 4 and the second shooting platform 5 during the movement. At this time, by setting the first intermediate limiter 17 and the second intermediate limiter 27, when the second shooting platform 5 is at the minimum safety distance S1 from the first shooting platform 4, the second mounting seat 14 and the fourth mounting seat 24 will contact the first intermediate limiter 17 and the second intermediate limiter 17 respectively (taking the first intermediate limiter 17 and the second intermediate limiter 27 as an example, which are respectively arranged on the first mounting seat 13 and the fourth mounting seat 24), the operator can be effectively reminded of the operation error and the collision between the first shooting platform 4 and the second shooting platform 5 can be effectively avoided.

[0049] The process of adjusting from the middle station to the double station is as follows: when the second shooting platform 5 is used as the middle station, the first shooting platform 4 and the second shooting platform 5 are at the minimum safety distance S1=A+B, and the second shooting platform 5 can only be adjusted to the second station first, and then the first shooting platform 4 is adjusted to the first station. The second end stopper 162 can be set so that when it contacts the second mounting seat 14, the second shooting platform 5 is aligned to the second station, and the position of the upper limit rib plate structure of the first mounting seat 13 can also be set so that when the upper limit rib plate structure of the first mounting seat 13 contacts the first displacement stopper 18, the first shooting platform 4 is aligned to the first station.

[0050] That is to say, taking the adjustment of the second shooting platform 5 for the intermediate station as an example, in the double-station state, the fourth mounting seat 24 is adjusted to contact with the fourth end limiter 262 (or the second mounting seat 14 is in contact with the second end limiter 162), and the limiting rib structure on the first mounting seat 13 is adjusted to contact with the first displacement limiter 18 (or the limiting rib structure on the third mounting seat 23 is in contact with the second displacement limiter 28); in the single-station state, the first mounting seat 13 is adjusted to contact with the first end limiter 161 (the third mounting seat 23 is in contact with the third end limiter 261), and the limiting rib structure on the second mounting seat 14 is adjusted to contact with the first displacement limiter 18 (or the limiting rib structure on the fourth mounting seat 24 is in contact with the second displacement limiter 28).

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
